________ caries blood from right ventricles to lungs.

  1. Superior vena cava

  2. Inferior vena cava

  3. Pulmonary arteries

  4. Pulmonary veins


Correct Option: C
Explanation:
The pulmonary artery is a blood vessel which delivers impure blood from right ventricles to lungs for the oxygenation. Pulmonary artery begins from the base of the right ventricle. As it leaves the heart it divides into two branches left and right pulmonary artery. The left and right branches bring their de-oxygenated blood to the corresponding left and right lungs.
So, the correct answer is 'Pulmonary arteries'.

The volume of blood pumped out by the two ventricles of human heart per minute is 

  1. $5L$

  2. $10L$

  3. $15L$

  4. $20L$


Correct Option: A

Which of the following is responsible to allow the flow of blood due to contraction of right ventricle ?

  1. Aorta

  2. Lymph Vessels

  3. Veins

  4. Blood Vessels


Correct Option: A

Pulmonary trunk originate from?

  1. Right Atrium

  2. Left Atrium

  3. Left ventricle

  4. Right ventricle


Correct Option: A
Explanation:

The pulmonary trunk is a significant human blood vessel from the right ventricle. It branches into the pulmonary arteries of the right and left that lead to the lungs.

So, the correct answer is 'Right Atrium'

The dorsal aorta arise from :- 

  1. Left ventricle

  2. Right ventricle

  3. Left atrium

  4. Right atrium


Correct Option: A

The pulmonary artery carries deoxygenated blood from the ........... to the lungs.

  1. Left ventricle

  2. Right ventricle

  3. Left auricle

  4. Right auricle


Correct Option: B
Explanation:

Pulmonary circulation carries blood to and from the lungs. They include the pulmonary artery (aorta) and its branches to the capillaries in the lungs, as well as the veins, that drain those capillaries. The pulmonary arteries carry blood low in oxygen from the right ventricle, while the pulmonary veins carry blood high in oxygen from the lungs into the left atrium. This circuit functions to eliminate carbon dioxide from the blood and replenish its supply of oxygen.

So, the correct answer is option B.

Which of the following statement is correct regarding humans?

  1. Arteries always carry oxygenated blood while veins always carry deoxygenated blood

  2. Arteries. are provided with valves while veins are devoid of valves

  3. Arteries always carry blood away from the heart, while veins always carry blood towards the heart

  4. Venous blood is returned to the left ventricle


Correct Option: C
Explanation:

Arteries carry blood oxygenated blood away from the heart. While the veins carry deoxygenated blood towards the heart.

Pulmonary artery carries deoxygenated blood to the lungs for oxygenation. Pulmonary vein brings oxygenated blood to heart. 
So, the correct answer is option C.

Pulmonary artery drains the deoxygenated blood from

  1. Right atrium

  2. Right ventricle

  3. Left atrium

  4. Left ventricle


Correct Option: B
Explanation:

Arteries carry oxygenated blood away from the heart.  Pulmonary artery carries the de-oxygenated blood from the right ventricle to the lungs for oxygenation.

So, the correct answer is option B.

The rate  of heart beat Per minute is highest in case of

  1. Elephant

  2. Whale

  3. Man

  4. Mouse


Correct Option: D
Explanation:

Under the normal conditions heart rate has an inverse relation with the size of the animal.

Body receives blood through arteries. Which one is out of place?

  1. Aorta

  2. Renal artery

  3. Coronary artery

  4. Pulmonary artery


Correct Option: D
Explanation:
A. Aorta is the largest artery in body which supplies blood from heart to rest of the body parts.
B. Renal arteries are blood vessels that branch from abdominal aorta and supply blood to the kidneys.
C. Coronary arteries supply the oxygenated blood to heart.
D. Pulmonary artery carries deoxygenated blood from right ventricle to the lungs. 
Hence, body receives blood through arteries except the lungs which receive deoxygenated blood through pulmonary artery.
So, the correct answer is 'Pulmonary artery'.
